I can't see allied models, but i can see axis models and any other model in the model folder. To clarify, when i go into hammer and on the map select entity button and select info player allied and put him on the map it appears as a solid greeb box, axis works fine as i said, and i have hammer 3.5. Problem is minor and does not affect anything else.

It must be a problem with the fgd, try replacing the current one with a new one and it should work!

Kehldon right, sounds like your fgd file.

Which one are you using?

I have the exact same problem. I never bothered putting any effort into trying to fix it, because, like you said, everything still works fine anyways... you just see green boxes instead of the Allied player model.

You don't need to worry about it, its a green box and the scaling is all correct, etc - but in game it will work juuuuussst fine :)
